Answer:
x = 1.19258 and x = −4.19258
Step-by-step explanation:
The given equation is :

Keep x terms on the left and move  the constant to the right side  by adding it on both sides.

Take half of the x term and square it.

then add the result to both sides

So,
x = 1.19258 and x = −4.19258
Hence, this is the required solution.
